A heart attack occurs when an artery that supplies the heart with blood and oxygen becomes blocked. The blockage is usually associated with cholesterol, a fatty substance found in the blood that tends to be deposited on the walls of blood vessels.
The condition is deadly and therefore requires immediate medical attention. However, since many are unaware of the signs of a heart attack, a person's reaction to its appearance may be delayed.
Most people associate heart attacks with chest pain that spreads to the jaw, neck, arms (usually left), shoulders, back, or abdomen. In fact, it is possible to experience more "subtle" symptoms that appear a week before the attack, Express reports.
"Two out of three people have symptoms such as shortness of breath and fatigue in the days or even weeks before a heart attack," explained the cardiologists.
Other lesser known signs include excessive sweating, dizziness, and nausea. If any such conditions appear, doctors urge you to immediately go to the hospital.
Earlier, experts talked about the simplest way to distinguish an impending heart attack. According to scientists, all you need to do is look at the language.
